| 聚對苯乙炔（PPV）材料具有電導(dǎo)、順磁、能量遷移和轉(zhuǎn)換等特性，其應(yīng)用研究很熱很廣，但其在吸聲領(lǐng)域尚未見報道過。將PPV與石墨烯、銅酞菁等材料按一定比例共混成膜，制得了新型導(dǎo)電復(fù)合薄膜吸聲材料。結(jié)果表明，該薄膜吸聲材料具有寬吸聲頻帶和強吸聲能力，在聲波125Hz～4000Hz頻率范圍內(nèi)的平均吸聲系數(shù)大于0.5，最大吸聲系數(shù)達(dá)到0.99，尤其是在中低頻范圍（125Hz～1000Hz）內(nèi)吸聲性能遠(yuǎn)比一般吸聲材料優(yōu)異。 |

| Poly-phenylene vinylene (PPV) materials have conductivity, paramagnetic, energy, migration and conversion characteristics, its application the research very hot very wide, but its sound absorption field has not been reported before. PPV and graphene, copper phthalocyanine, etc. blend deposition of material by a certain percentage, the prepared novel conductive composite film sound absorbing material. The results showed that the film sound absorbing material having a wide the sound absorption bands and strong absorption capacity, the average absorption coefficient in the acoustic frequency range of 125Hz ~ 4000Hz is greater than 0.5, a maximum absorption coefficient of 0.99, especially in the low-frequency range (125Hz ~ 1000Hz) within the sound absorption performance than the general sound-absorbing material is excellent. |
